Contacta Above the Counter Loop System

Contacta Above the Counter Loop System

Product Code: 954.017UK
Brand: AVSL
More Information

An over-counter loop system, providing clear communication with hearing aid wearers, especially where background noise is a problem or clear speech is restricted. The aerial is contained within the sign, which fixes to a counter or desk surface, enabling users to easily spot the loop and get maximum benefit from it. The unit can be fitted in many positions due to its low-profile structure. Complies with the following standards: CE, ROHS and WEEE compliant; BS EN 60118-4 in correct installations.
